Specification of Letters Patent.

Patented Aug. 9,

Application filed March 29, 1918. Serial N 0. 225,517.

To all whom it may con cern Be it known that I, EDWARD M. HEYLMAN, a citizen of the United States, and a resident of South Bend, in the county of St. Joseph have invented certain new and useful Improvements in Flows; and I do hereby declare the following to be a. full, clear, and exact description of the invention, suchfas will enable others skilled in the art'to which it. appertains to make and use the same.

This invention relates to improvements in plows and 'more particularly to lifting means for the vention being to provide simple and eflicient means cooperable with the mounting of the rear furrow wheel and operable by power from another wheel of the plow and located at the rear end of the plow beam or frame to control the raising and lowering of the.

soil-engaging devices.

A further object is to provlde simple and efli'cient means in power mechanism for locking parts of' such mechanism in such manner that the plow will be locked either in a raised position, or locked down to its working'position whereby the weight ofthe wheels will be brought to bear on the plo-w bases when in a working position to keep them at work in hard ground at a uniform depth.

A further object is to improve the construction of power lift mechanism and enhance the efficiency of the same in various respects. p I lVith this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims. i

In the accompanying drawings; Figure 1 isa plan view of a -plow embodying my improvements; Fig. 2 is a view in side eleva- ,tion showing the positions of the parts associated with the rear furrow wheel when the plow is elevated; Fig. 3. is a. similar view showing the positions of the same parts when the plow bases are in workingposltion; Fig. 4 is a plan view of the pivoted bracket in which the rear wheel axle is mounted; Fig. 5 is a separate view of the bracket in which the rear wheel axle bracket is pivotally mounted; Fig. 6 is a view partly in section, showing the crank shaft of the same,-one object of the in- "shaft 6. A bracket 7 8 is aview showing the connections between the operating bar and the front furrow wheel mounting for'efiecting the raising of the frontend of the frame when the rear end 1s raised, and Figs. 9 and 10 are secand the mounting of said operating tional vviews showing the clutch devices,

gearing and locking means of the power lift, mechanism.

The frame of the plow structure comprises a beam 1 and a forward cross bar 2 with which latter the beam 1 is connected b means of a bracket or connector 3. The beam has secured thereto a plurality of brackets or standards 4 on which soil-engaging devices 5 are mounted. In the drawing I have illustrated the soil-engaging devices in the form of disks but it is evident that plow bases of the mold-board and share type might be employed.

Thefront cross bar 2 of the frame may be made angular in cross-section and it is tubular to form a bearing for a transverse is secured to the angular cross bar 2 and is made with an upright tubular portion 8 which forms a bearing for the standard portion 9 of the axle of a front furrow wheel 10. mounted upon the upper end of the standard axle -9. A hand lever 12 is pivoted A segment bracket 11 isto the segment bracket 11 and is provided against turning (as hereinafter explained) and the hand lever 12 is operatechthe forward portion of the framemay be raised or lowered.

A frame 15 is securely bolted to the rear end of the beam 1 and is made with tubular portions 16, 17 which provide bearings, respectively, for a crank shaft 18 and the axle 19 of a land wheel 20. The axle 19 is formed with a crank 21 on which the hub of the land wheel is mounted and said hub is provided with a sprocket wheel 22 from which motion is transmitted by a drive :chain 23 to a sprocket wheel 24 mounted on the 14 at one end of the axle 19. The axle 19 also carriesahpinion,

the crank shaft 18. Clutch mechanism 25 is located between the pinion 25 and the. sprocket wheel 24, and controlled by a cord 26 connected with a trip lever 27.

The rear end of the plow structure is sup ported at the furrow side thereof, by a rear ing this wheel and operating it to provide rear wheel lifting means for the plow will now be explained.

A bracket 29 is securely bolted to the rear standard bracket 4 of the plow frame and projects rearwardly therefrom. The

.-bracket 29 is provided with rearwardly projecting lugs or ears 30 spaced apart for the accommodation of an axle bracket 31, the latter being pivotally connected with said lugs or ears by a suitable pin 32 and said bracket 31 is formed with a tubular portion which receives the upper part of the axle 33 of the rear furrow wheel 28. The axle bracket 31 is made with -a flanged arnr 31 whichjreceives'the inclined portion of the standard axle 33. and permits'a limited pivotal movement of said axle. The bracket 29' is made with a transverse tubular portion 34 which constitutes a bearing for a shaft 35.

. This shaft is provided at one end with a crank arm 36, with which the upper end of a link 37 is pivotally connected, the, lower end of said link being pivotally attached to an arm 38 projecting forwardly from the lower portion of the axle bracket 31. To

ating bar 43, the rear end of which latter the other end of the shaft 35, an arm 39 is secured and projects upwardly therefrom. The arm 39 is provided at or near its upper end with a transverse hole in which the shank 40 of an internally threaded sleeve 41 is loosely mounted, said sleeve being disposed at right angles to the shank 40. These devices afford an adjustable and pivotal connection of a rod'42 with the arm 39, said rod having a threaded portion passing through the sleeve 41. The other end of the rod 42 ispivotally connected with an actuis connected with the crank of the shaft 18 of the power mechanism. Several holes 42 may be provided in the actuating bar 43 whereby the rod 42 may be 'adjustably attached thereto, so that the rear disk arms can be adjusted on the main beam-for changing the width of cut of each disk from 8, 9 and 10 inches. The sleeve 41 can be adjusted on the threaded portions of rod 42 to allow for the adjusting .of a screw 45 in an arm 44 on the bracket 31., Any movement of the rear furrow wheel'up or down when the plow is in working position will be prevented, it being desirable that the weight of K the rear wheel shall be alwaysvon the disks furrow wheel 28, and the manner of mount-g disks or plow bodies. a The forward end of the b'ar43 is secured to a segment bracket 48 and the latter is sup? '75 ment of the rod 42 and motion to p parted, through the arm 39 to the crank 105 screw the rear furrow wheel 28 m'ayf be s0 adjusted that its lower peripheral edge shall aline with the lower cutting edges of the ported by an arm 49, the upper end of said link being bifurcated and pivotally attached to the segment bracket 48by means of a pin 50 and its lower end is adjustably-secured to the shaft 6. A hand lever 51 is mounted on 8.0 I the pivot pin 50 and carries a suitable detentl to engage the segment of the segment bracket 48. An arm 52 is rigidly secured to the hand lever 51 and to this arm, one end I p of a rod 53 is connected, the other end rof .85

said rod being attached to an arm 54 secured to the land wheel axle 19. "A bal'ance'spring 55 is connected with the arm 54'a'nd with the lower depending portion 56 ofv the arm 49.

By means ofthe lever 51, the crank axle 19 of the land wheel may be-operated to effect] leveling of the rear end 'of'the plow struc.- ture, while the front portion .ofthe latter may be leveled by manipulation of 'the lever 12.

When it is desired to raise'the plow, the operatorwill manipulate the cord 26 to throw the power mechanism into action, so that motion shall be transmitted from the hub of the land wheel 2 to the crank shaft 18. The turning of this crank shaft will cause the actuating bar 43 to move for- I wardly and this will cause a forwardmovebe im-- sl1aft 35. As the latter shaft turns, motion will be. imparted by thelink 37 to the arm 38 of the axle bracket 31, thus causing the latter to be moved from the position shown' in Fig. 3 to the position shown in Fig. 2 and 100' the'plow' structure to be ralsed 9n the rear furrow wheel 28.

When the actuating bar 43 is moved forwardly as above described, the supporting link 49, with which the forward end ofsaid 11a bar-is connected (through the medium of-the segment bracket 48) will be moved forwardly, thus causing the. crank shaft 6. to turn and impart a lifting action to the forward end of the plow frame, through the 129 medium of the connections between said crank shaft 6 and the standard axle'9 of I" the front furrow wheel 10.

The forward movement, of the actuating bar-43 and arm 49, will also cause a forward ,movement of the segment bracket 48 and the hand lever 51 which is locked to the segment by its 'detent. As the lever thus moves forwardly, motion will beimparted, throu h the arm 52 and rod 53 to the arm 54 on t e larger gear 26 and consequently a one-half rotation of the crank shaft 18. It will be observed that the actuating bar 43 will normally bear a dead-center relation to the axis of the crank shaft 18 and the forward connection of the actuating bar, when the'plow is in working position, as shown in Figs. '1'

and 3, and that when the shaft 18 shall have been'turned a one-half rotation during the lifting operation, the actuating bar will have again assumed a dead center relation to the axis of .the crank shaft 18 as shown in Fig. 2-and it will thus be seen that a dead-center lock is provided for the plow when the latter is in either its working or in its raised position. In order that the gearing shall be held in position at each half rotation of the shaft 18 and thus insure the maintenance of the dead-center relation of the actuating bar to the axis of the shaft 18-when the plow is in either working or raised position, a locking lever 57 is provided. This lever is pivoted at 58 and is provided with a V- shaped or cam notch '59 for engagement with one or another of two pins 60 (having rollers 61 thereon) located at diametrically opposite points on the gear 26, proper engagement of the locking other of said ins bein insured by the action of asprlng 62. hisspring is attached atone end to the locking lever and its other end may be attached to the trip lever 27.

It is apparent that when it is desired to lower the plow, the trip lever 27' may. be operated to cause the gear 26 to overcome the locking means and permit the plow to descend to and become locked in working position.

Various slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope and hence I do not wish to restrict myself to the precise details here.- in set forth.
